Picking a refrigeration mechanic looks like picking any other tradesman until something fails on a Saturday and the wrong choice costs you a weekend of stock. A few specific checks cut through the noise — here's what actually separates the operators worth keeping in your phone from the ones who'll quietly disappear after the deposit clears. Especially relevant for premium hospitality areas like Killcare where downtime is genuinely expensive.
1. Valid ARCtick licence
It's legally required to handle refrigerants in Australia. No exceptions. If a tradesman quotes you on a refrigeration repair without an ARCtick licence number you can verify, walk away — whatever they do next is illegal, uninsurable, and uses up gas they're not allowed to buy. The ARCtick number should be visible on quotes, invoices, and on the licensee's website. Verifying it takes 30 seconds at the public registry.
2. Real Google reviews — read the long ones
Star count is easy to game. Detailed reviews are not. Read the three or four longest reviews on a tradesman's Google profile and look for specifics — the type of job, what was done, whether anything went wrong and how it was handled. A real customer who took ten minutes to write a review usually says something useful. A fake review usually doesn't.
Owner responses matter too. A tradesman who replies thoughtfully to every review — including the negative ones — is one who pays attention to feedback.
3. Response time — ask what “same day” means
“Same-day callouts” can mean “a technician will be there before close of business” or it can mean “we'll get to it eventually today, maybe.” Ask specifically. A tradesman with a clear answer (“I aim to be on site within 4 hours of an emergency call during business hours”) is one who's actually thought about it.
4. Commercial vs residential experience
Commercial refrigeration and residential air conditioning are different skill sets. A tradesman who only ever services home AC will struggle with a commercial walk-in cool room. Ask directly: how many cool rooms have you serviced? How many cafes? What's the biggest commercial install you've done? The answers will tell you whether you've found a fit.
5. Transparent quoting — beware “too cheap”
A quote that comes in 40% below every other tradesman in town is rarely a great deal. It's usually a foot in the door for upsells once work has started. Look for itemised quotes that list parts, labour, and call-out separately. Ask what's included and what isn't. The cheapest quote is rarely the cheapest job by the time it's finished.
6. Warranty on work
Reputable tradesmen warranty their work. Ask what the warranty covers, how long it runs, and what voids it. A vague answer here is a warning sign.
The maintenance relationship
The single biggest predictor of low refrigeration costs over a five-year horizon isn't any of these individually — it's having a regular maintenance relationship with a Central Coast tradesman who knows your equipment. The technician who serviced your cool room last quarter walks in already knowing what they're looking at. The first-time emergency callout doesn't.
